摘要：The present invention relates to a composite comprising a polymer and a blue phase liquid crystal (BPLC). The polymer is a crosslinked and non-liquid crystalline polymer, the BPLC is dispersed in said polymer, and the ratio of the polymer to the BPLC by weight (W p W l ) satisfies the relationship:12 : 88 < W p /W l ‰¤ 30 : 70, wherein the W p is the weight of the polymer, and W l is the weight of the BPLC. The composite exhibits a very wide temperature range of blue phase of the BPLC, and can respond to an electric field at a millisecond level. The composite has an excellent stability, and a lower viscosity, while a wide viewing angle and a low driving voltage can be achieved. The invention also provides a method for preparing the composite, and a LCD device comprising the composite. The method of the present invention is simple and efficient.
